Overview
Abdominal CT scan may be helpful in the diagnosis of portal vein thrombosis. Findings on CT scan suggestive of hyperattenuating material in the portal vein lumen, nonenhanced intraluminal-filling defect.
CT scan
- Abdominal CT scan may be helpful in the diagnosis of portal vein thrombosis. Findings on CT scan diagnostic of portal vein thrombosis include:[1][2][3][4][5][6]
- CT scan without contrast:
- Hyperattenuating material in the portal vein lumen
- Nonenhanced intraluminal-filling defect
- CT scan with contrast:
- Lack of luminal enhancement, increased hepatic enhancement in the arterial phase
- Decreased hepatic enhancement in the portal phase
- CT scan without contrast:
